Network discovery method, device, base station and control base station in hybrid home network

Abstract

The invention discloses a network discovery method, device, base station and control base station in a hybrid home network, belonging to the technical field of communication. The method includes: the station initiates a network discovery process according to the target network label; when the station does not access the target network corresponding to the target network label within the first preset time period, and does not search for a network with the same target network as the station When other stations are not associated, switch the first port currently used for sending to the second port; send a new station report message to the control station of the target network through this port, so that the control station controls the associated stations in its network to send discovering the beacon; and then allowing the station to discover the target network according to the discovering beacon. The invention speeds up the network discovery process by correctly selecting the target network label and waking up the associated stations in the dormant state in advance and arranging them to send discovery beacons.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a network discovery method, device, base station and control base station in a hybrid home network. Background technique [0002] PLC (Power Line Communications), as a communication method using power line as a communication transmission medium, has received extensive attention in the field of network technology and multimedia technology, especially in home broadband networks and smart grids. [0003] A PLC network consists of several common sites and a control site in a management position. The control station sends a central beacon in each beacon period, and the central beacon contains scheduling information and other management and control information. At the same time, the control station will also schedule some stations to send discovery beacons in each beacon period, and each station (including the control station) will send discovery beacons accordin...

Problems solved by technology

[0010] When the unassociated PLC station has multiple target network NIDs, since the unassociated PLC station cannot determine the correct NID before the network discovery process, the unassociated PLC station needs to try each NID one by one for network discovery, thus Causes longer network discovery times

At the same time, factors such as whether all or part of the PLC stations in the target network are in a dormant state, and the distance between the unassociated PLC stations and the target network will also affect the speed at which the unassociated PLC stations discover the central beacon of the target network, so that the unassociated PLC stations can discover the central beacon of the target network. The time to associate PLC sites for network discovery is affected, thus causing unnecessary waste of resources
